Taking A mining area as an example,soil heavy metal pollution in open-pit coal mining area was treated.A method of soil heavy metal pollution assessment and ecological pollution risk assessment in mining area was introduced.The geological accumulation index method was used to evaluate the element type,pollution degree and spatial distribution characteristics of heavy metal pollution,and the ecological risk index model was used to carry out the evaluation,so as to improve the understanding of relevant workers on the heavy metal pollution in the mining area,which provided support for the improvement of the ecological environment in the mining area,and confirmed that the method proposed in the study had certain application value.
